SQL PADD LET avec zéros
If you want nulls to show as '000'
It might be an integer -- then you would want
SELECT RIGHT('000'+CAST(field AS VARCHAR(3)),3)
As required by the question this answer only works
if the length <= 3, if you want something larger you need
to change the string constant and the two integer constants t
o the width needed. eg '0000' and VARCHAR(4)),4
